Optoma's DLP PK101 pico projector up for pre-order at $399.99

"Coming soon," huh? Soon, indeed. Optoma's DLP-based pico projector, which is formally known as the EP-PK-101 (or PK101 in some circles), is now up for pre-order at Amazon. So, just how much will you pay for a 4-ounce beamer that you can carry in your left front pocket? If your answer is anything less than $399.99, you're out of luck here.
